Overview of the trial data
The trial data for Aclidinium Bromide describes one completed study in people with Chronic Obstructive Pulmonary Disease (COPD), a long-term lung condition that makes breathing difficult.[1] The study asks whether one inhaled treatment plan works better than another for improving clinical control in patients with COPD.[1]
Study design and phase
This was an interventional study, which means researchers assigned treatments and compared the results between groups.[1] It was also an open-label, pragmatic, randomized, and controlled trial in Phase 3.[1] Phase 3 studies usually involve larger groups and are designed to compare how well treatments work in practice.[1]
Who the trial is for
The main target group was high-risk GOLD B patients with COPD.[1] GOLD B is a COPD category used to describe a specific patient group in the study, and “high-risk” means the patients may need closer treatment control.[1] The trial enrolled 1,028 participants, showing that it was a fairly large comparison study.[1]
Treatments compared in the study
The study compared Trelegy® with LABA-LAMA treatment to see which option gave better clinical control.[1] LABA-LAMA means a combination of two long-acting inhaled medicines, and the trial data lists many branded inhaled products used in these treatment groups.[1] The source data does not give a full breakdown of all randomization groups, but it clearly shows a comparison between Trelegy® and LABA-LAMA-based care.[1]
Main outcome measured
The main outcome was whether a patient stayed persistently controlled at all study visits.[1] To count as controlled, the patient had to meet the study criteria at month 3, 6, 9, and 12.[1] The trial also used a validated composite endpoint, which means the result combined more than one important measure, including the domains called stability and impact.[1]
What the study result means for patients
This trial was designed to find out whether one inhaled treatment strategy could improve daily disease control in COPD better than another.[1] Because the study is completed, it adds evidence about treatment comparison in a real-world style setting for patients with COPD.[1] The data shown here is focused on treatment effectiveness and control over time, not on basic drug science.[1]
